P0124 - Throttle/Pedal Position Sensor/Switch A Circuit Intermittent

Throttle or pedal position signal is intermittent.

Treat the code as the starting point: compare symptoms, likely causes, and repair paths before pricing parts or moving into an estimate.

Code Overview

Throttle or pedal position signal is intermittent.

Common Causes

• Worn TPS/APP sensor
• Loose connector
• Wiring issue
• Throttle body fault

Diagnostic Steps

1. Monitor TPS/APP sweep for dropouts
2. Inspect connector pins for spread terminals
3. Check throttle body and harness movement

Likely Repairs & Cost Guides

Use symptoms, scan data, and quick checks to confirm the likely repair path before pricing parts. The estimator helps compare repair paths before replacing anything unnecessarily.

Browse nearby code-family pages when the same fault pattern overlaps across systems, such as misfire, lean fuel trim, EVAP sealing, cooling, or charging faults.

Next Steps

Move from code lookup to diagnosis, then estimate the likely repair only after symptoms, causes, and checks point to the same path.
